My invention relates to portable drawing boards and particularly'to animprovement on the construction shown in my, copending applicationSerialN0. 19 1,10? :filed 25,

5 1927. I I l q An object of my invention is to provide a complete andcompact drawing kit of anew and improved design, in which I utilize abox or container of relatively rectangular shape and having a'slidingdrawer therein adapted to contain various drawing papers and equipment;i

Means are provided on this box for retaining a sheet ofpaper in flatposition on the top 1 of the box, as well as to receivea tablet.

In a device of this character the most important requisites are suitablesize and weight, with provision for carrying materials and means forinsuring comparatively accurate drawings with a T-square and triangles.

In my present improvementI have incorporated means for insuring a morerigid constructionof the box as .well as means for insuring a moreuniform and even bearing surface for the T-square.

A further improvement in'my present device relates to the, means forsecuring the drawer within the box, whereby the box may be inserted andremoved with the utmost fa The invention will be more readily understoodby reference to the accompanying drawing, in whichy r I Fig. 1 is aplanview partly in section of my improved drawing kit; A V Fig. 2 1satransverse sectional view of my improved device onthe line '22 of Fig.1; Fig. 3 is a side view showing the aperture in the side wall and thedrawer clip therein, 40 and i i Fig. 4 is a sectional View slightlyenlarged on the line 4 -4: of Fig. 1. I

By reference to the drawing it Wlll beseen that I have provided arectangular metal box 4 having top and bottom walls 10,11, respectively,end walls 12, and an indented side wall 131 The edge of the bottom wall11 is doubled back on itself as at 14: and the edge of the top wall isbent back as at 15. A longitudinal head 16 is formed; in .the'metal of1925. Serial no. 288,173.

Inwithdrawingthe drawer, there is a tendency forthe upper sheets of thepad of paper to catch on the inturned' edge 15 of the top wall and thisis obviated by providing the bead 16 in close proximity thereto. I o aAs a means for securing the drawer in place and for facilitating itsejection from the box, I provide a finger hole 23 in the wall 13, thehole being located substantially midway between the ends of the box. Thefastening clip consists of a spring tongue 24, riveted or welded to thefloor of the drawer and having a hooko25 formed near its end terminatingin an upstanding arm 26, the arm and hook projecting through theaperture 23 in the back wall of the box. portion 26 is located atsubstantially the center of the hole 23, and pressure by the finger, onthe arm,-serves to rock it sufficiently to elevate thelock 25 out ofengagement with the catch 23A located in a plane with the wall 13;continued pressure on the arm will cause the finger to contact the backwall 19 of the drawer, and serve to push the drawer out of the box. Thusthe action 'of-unlatching the box serves to also push the drawer-out.

In the top wall of thevbox and located nearthe rear margin thereof arethree narrow longitudinal slits 27. These slits are located suificientlyclose to the rear margin or back the drawer and any dirt or moisturethat may drop through the'slits will not drop in the drawer. paperholding bands orclips 28, having at one end a hook 29 adapted to enter aslit and at the other end a rebentresilient portion 30. The clips arecomposed of spring metal and normally occupy abowed position asindicated in dotted lines in Fig. 2. However, when a sheet of paper or acard are to be held in place on the topof the box, theyare placed inposition as indicated in Figs. 2 and 4 the .hook 29 inserted in a slit27, and the opposite endpushed downward until the end 30 engages beneaththe free edge of the top wall. Due tothe construction of the clip 'and'the cooperating parts, the clip will function 'whether the drawer isclosed as shown in Fig. 2 or partly open as indicated in dotted lines inFig. 1. By the provision of three equally spaced slits and elongatingthe slits to the extent indicated, I am able to hold in placecomparatively small cards or large sheets of paper as required. YAnotherpurpose for the slits is. to provide "for cooperation therewithof tongues or lugs on a metal back for a pad of paper. This is describedand claimed in detail in a co-pending application and is notspecifically disclosed and claimed'herein. For convenience in handling,the T-square,spring clips, pad of paper and other drawing equipment, allare intended to bereceived within the drawer.

In order to insure atight fit of the drawer when in closed positionwithout too close fitting of the parts, I provide at the back edge ofthebox and fixed to the upper wall a wedge member 31 so placed that therear end of the drawer is caused to contact the same The end of the.

wall of the box, so that they are not above The slits are intended toreceive the drawer-catch The back wall construction notonly provides arigid. plane surface for contact by the T-square head, but insures themaintenance of this surface notwithstanding relatively rough handlingOf'the box and the hammering of the drawer in being returned to itsclosed position, The pockets provided by the beads serve to trap air andinsure somewhat of limited cushioning effect even though the drawer becarelessly returned.

Other modifications and variations may be made in the constructionshown, and I do not wish to be limited except as indicated in'theappendedclaims.

I claim:

1. In combination, a metal box and a drawer slidable therein, the topwall ofthe box being adapted for use as a support for drawing paper, aside wall of the box being shaped to provide a narrow continuous planesurface near the said top wall for engagement by the head of a T-squareand a relatively indented portion adapted to act as a stop for saiddrawer.
